Sacred space is by definition liminal space. Because we are not in control and not the center, something genuinely new can happen. Here we are capable of seeing something beyond self-interest, self-will, and security concerns. True sacred space allows alternative consciousness to emerge.
Peace always begins within each of us. Our ability to create in the world depends on our ability, first, to work to create peace in our own lives. It's much easier to advocate peace on Earth than it is to be able to bring peace your own home. Or your own heart.
